Product Details


Technical Description 
 
This training system provides a comprehensive experimental introduction to the fundamentals of process control using an example of level control.

All components are clearly laid out on a vertical panel. The large-format process diagram provides an aid to understanding. A pump transfers water from a storage tank into the transparent process tank. The level is measured by an electronic pressure transducer installed at the base of the process tank. The controller used is a state-of-the-art digital industrial controller. The actuator in the control loop is an electromagnetic proportional valve. A ball valve in the outlet enables defined disturbance variables to be generated. The controlled variable X and the manipulating variable Y can be tapped as analogue signals at lab jacks. This enables external recording equipment, such as a plotter or an oscilloscope, to be connected. 
An instrumentation and control software (RT 650.40) with interface module (USB) is available as an accessory. This enables the key process variables to be represented, and control functions executed.
 
The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments.
 
Learning Objectives / Experiments

- Introduction to the fundamentals of process control
- Familiarisation with latest industrial process control
  components: controllers, transducers, actuators
- Operation and parameter setting of a multi-
  functional state-of-the-art digital controller: e.g.
  parameter setting as P, PI and PID controller
- Investigation of disturbance and control response
- Influence of different control parameters on stability
  and control quality
- Investigation of the properties of the open and
  closed control loops
- Processing of process variables using external
  equipment, e.g. plotter or oscilloscope
- In conjunction with accessory RT 650.40:
  Familiarisation with and use of I&C software
